Change Line Color in Chateau?

I'm trying to change the color of the lines that divide the columns and posts in the Chateau theme. Also, I would like to remove the line around the header image. Lines, borders, strokes -- I'm not sure what to call them.

I think I finally figured out how to change the line colors. Now I'm trying to refine the type. I'm trying to increase the font size of the body copy and side menu. I'd also like to change to color of the body copy and the links (both on the side menu and above the body copy).

Thanks. All that helped a lot. I still can't change the color of the links on the side menu but what I have will work. There's a couple other lines like the ones around photos that I can't change, but I have everything about 95% of where I want it, so I can live with it.

First off, it appears as if you have pasted the entire stylesheet into the CSS edit window. That can cause issues. Generally what you want to do is put only the specific selectors, and the specific declarations you are changing into the CSS edit window and make sure that "add to existing..." is selected.

Secondly, I see the #content stuff in your CSS, but you did not edit the hex color code. It is exactly what it was originally.

This works. I just did it on my test blog, but with you having pasted the entire stylesheet there might be something in what you pasted that is overriding the change. That is one of the problems you will run into doing it the way you have.

Add the following at the very bottom of all the stuff you have in the CSS edit window. Very end. I used the "important" attribute to force it to override everything else. Edit the color code to your desired color.

Wow, this is all perfect. Thanks again. If it's not too much trouble, could you help me with one last thing? When you view each blog entry on it's own, towards the bottom of the page below the "Like This" link and above the "Previous Post" link there is a white line. How can I change the color of this?

Thanks again for all your help. I'm not a coding guy so I'm learning as I go.
